Abstract: Methods and systems for analyzing a sample and generating a predictive model using cavity ring-down spectroscopy are disclosed. At least part of a sample is loaded in a ring-down cavity. For each of a set of wavelengths, a laser beam is generated and directed into the ring-down cavity. The laser beam entering the ring-down cavity is extinguished. Light intensity decay data for light exiting the ring-down cavity is registered via a light intensity sensor system. A probability is determined from the light intensity decay data for the set of wavelengths that a subject from which the sample was received has a physiological condition or a degree of the physiological condition at least indirectly using a dataset of light intensity decay data for previously analyzed samples for which the presence or the absence of the physiological condition or the degree of the physiological condition have been identified.

Abstract: A tiny and portable micro-spectrometer deployable in a bullet-like form that is inexpensive to the point that it can even be disposable is described. The device is based on the micro-spectrometer that uses the Fresnel diffraction principle that allows a tiny implementation with a nanometer resolving power of spectral signal. A bullet-like micro-spectrometer has an integration of a super capacitor as a power source, a charging coil for the super capacitor, an LED or laser diode light source and driver, an analog to digital converter (ADC) circuit, and a telemetry system with antenna string. An LED or laser diode runs in a burst mode to generate deep or vacuum UV to excite target material. When the excited state of target material undergoes a singlet or triplet transition, this transition process yields fluorescence or luminescence which is a material-dependent. The micro-spectrometer senses and uses this spectral emission from material to identify the spectral signature of the targeted material. The data is converted by an ADC and transmitted to a receiving station.

Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system comprises: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further comprises a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: A data set is stored in memory circuitry that is indicative of a state of a semiconductor fabrication process or of semiconductor structure fabricated thereby. Features in the data set are discernable to an extent limited by a data resolution. A machine-learning model comprising parameters having respective values assigned thereto as constrained by a model training process is also stored in the memory circuitry. Processor circuitry communicatively coupled to the memory circuitry generates an output data set from the data set in accordance with the machine-learning model such that features in the output data set are discernable to an extent limited by an output data resolution that is finer than the data resolution of the data set.
